Action
Notice of proposed rulemaking (NPRM).
Summary
The Federal Aviation Administration proposes to amend the airworthiness standards for transport category airplanes concerning flight guidance systems. The proposed standards address the performance, safety, failure protection, alerting, and basic annunciation of these systems. This proposed rule is necessary to address flight guidance system vulnerabilities and to consolidate and standardize regulations for functions within those systems. This proposed rule would also update the current regulations regarding the latest technology and functionality. Adopting this proposal would eliminate significant regulatory differences between the airworthiness standards of the U.S. and the Joint Aviation Authorities of Europe.
